Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Estimating Soil Electrical Parameters in the Canadian High Arctic From Impedance Measurements of the MIST Antenna Above the Surface

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The MIST experiment aims to detect the cosmological 21‐cm signal through sky observations at 25–125 MHz using a wide‐beam antenna. The antenna is mounted above the soil and the beam characteristics are highly dependent on the soil's electrical properties.

Accuracy and Scaling Factors of Non‐Empirical Double‐Hybrid Density Functionals for Harmonic and Fundamental Frequencies (And ZPVE)

open access: yesJournal of Computational Chemistry, Volume 47, Issue 1, 05 January 2026.
Scaled factors for non‐empirical double‐hybrid density functionals (i.e., the QIDH family of models) provide average errors of 20 cm−1$$ 20\ {\mathrm{cm}}^{-1} $$ for ahrmonic and fundamental frequencies and 0.1 kcal/mol for ZPVE. ABSTRACT We obtain here scaling factors for harmonic and fundamental vibrational frequencies, as well as for Zero‐Point ...
